EKF Based Mobile Robot Localization [PDF]
2012 Third International Conference on Emerging Security Technologies, 2012 Localization plays a significant role in the autonomous navigation of a mobile robot. This paper investigates mobile robot localization based on Extended Kalman Filter(EKF) algorithm and a feature based map. Corner angles in the environment are detected as the features, and the detailed processes of feature extraction are described.

Convergence and Consistency Analysis for a 3-D Invariant-EKF SLAM
IEEE Robotics and Automation Letters, 2017 © 2016 IEEE. In this letter, we investigate the convergence and consistency properties of an invariant-extended Kalman filter (RI-EKF) based simultaneous localization and mapping (SLAM) algorithm. Basic convergence properties of this algorithm are proven.

Automatic Eye-in-Hand Calibration using EKF
CoRR, 2022 In this paper, a self-calibration approach for eye-in-hand robots using SLAM is considered. The goal is to calibrate the positioning of a robotic arm, with a camera mounted on the end-effector automatically using a SLAM-based method like Extended Kalman Filter (EKF).

Sensorless FOC Strategy for Current Sensor Faults in Three-Phase Induction Motor Drives [PDF]
Journal of Operation and Automation in Power Engineering, 2023 Current sensors are required in Field-Oriented Control (FOC) strategies of Three-Phase Induction Motor (TPIM) drives. Nevertheless, the current sensors are subject to different electrical/mechanical faults which reduce the safety and dependability of the

EKF-based output-voltage regulation of 3rd-order LCC resonant converters subject to load variations
, 2010 The extended Kalman filter (EKF) is proposed as a candidate methodology to eliminate the requirement for isolated feedback sensors (components that contribute to complexity, component count and cost), for the closed-loop regulation of 3rd-order LCC ...

Modified EKF Algorithm Considering Aging to Estimate the SOC of Lithium-ion Battery
Journal of Harbin University of Science and Technology, 2022 The State of Charge (SOC) of lithium battery is one of the basic parameters of battery management system (BMS). The accurate estimation of SOC is the basis of BMS reliability and accuracy. In order to improve the estimation accuracy of SOC, an estimation

Consistency of the EKF-SLAM Algorithm [PDF]
2006 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006 This paper presents an analysis of the extended Kalman filter formulation of simultaneous localisation and mapping (EKF-SLAM). We show that the algorithm produces very optimistic estimates once the "true" uncertainty in vehicle heading exceeds a limit.
